Islands of Adventure's Dueling Dragons roller coaster was rethemed to the Tri-Wizard Tournament's "Dragon Challenge" for the Wizarding World of Harry Potter when the land opened in 2010. Like on Dueling Dragons, there are two interlocking coasters, renamed the Chinese Fireball and the Hungarian Horntail. The two Bolliger & Mabillard inverted coasters no longer "duel," riding next to one another at points on the track, due to several incidents in the past where passengers lost personal items, such as glasses and cell phones, that flew toward passengers on the other track at the moment as it was passing. The ride closed on Sept. 4, 2017, to make way for a new Potter-themed coaster experience.
